Abstract
A novel PE material is devised showing excellent mechanical/optical properties and process ability, e.g. for film extrusion. The polyethylene of the invention is produced in one single e.g. gas phase reactor.
Claims34
A polyethylene comprising at least one C3-C20-olefine-comonomer polymerized to ethylene, wherein the polyethylene has a dart drop impact value, as measured by ASTM D 1709:2005 Method A on 25 μm blown films, of at least 1200 g, has a haze of <20% and has been polymerized in a gas phase reactor.
A polyethylene comprising at least one C3-C20-olefine-comonomer polymerized to ethylene, wherein the polyethylene, has a dart drop impact value, as measured by ASTM D 1709:2005 Method A on 25 μm blown films, of at least 1200 g, has a haze of <20% and is comprises a high temperature peak weight fraction (% HT) above a temperature threshold of 80° C. in CRYSTAF® analysis in an amount of at least 5% of the total weight of the polyethylene composition.
